The correct answers are:
• Liver cells are abundant in SER.
This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.
• The testes and ovaries are tissue types whose cells are abundant in SER.
This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).
• Cholesterol is made in the SER.
ER is the organelle at which all membrane lipids are synthesized.
• Phospholipids are synthesized from cytosolic water soluble precursor molecules.
Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.

The photo is showing human karyotype. Haploid=n, diploid=2n. The picture shown 23 pair of chromosome which mean n=23. Therefore, diploid number of this individual is 46.
Answer:
Alleles refer to the alternative form of the same gene. These are mainly of two types: dominant and recessive allele.
The dominant allele is the which mask the effect of another allele in a heterozygous condition. The allele which is masked or which is not able to express itself in a heterozygous condition is termed as a recessive allele.
For example, T (codes for tallness of a plant) is dominant over t which codes for a dwarf trait.
The organisms that contain the same allele for a particular trait is said to be homozygous for that trait. For example, TT and tt.
In contrast, if the organism contains different alleles for a particular trait, it is termed as heterozygous for that particular trait. For example, Tt.
Thus, the first, second, third and fourth blank can be correctly filled with dominant, recessive, homozygous, and heterozygous respectively.
Answer: If wilting is due to a lack of water at the roots, carefully re-water the soil or compost. Overwatering and flooding the growing medium can cause further root damage, which then leads to further wilting. If it is due to damage to the stems, prune out all those parts that are affected.
